hey everyone, got my first jeep a 2008 wrangler x about a month and a half ago and i absolutely love it and am glad to be a part of the community..unforunately im already having some problems... got an ETC light and the engine is slow to rev up and then drops down when up to speed.. everything goes back to normal after i restart the engine but then comes back after a while. this has only happened in the past couple days and i dont know what to do. is this something i can fix myself? any suggestions would be appreciated. again im glad to be here and looking forward to meeting some cool new people and learning more about my jeep.
